'The TkZinc widget has been developped by the CENA for its own
need of prototyping environment. It is now heavily used by more
than a dozen living projects involving advanced HMI. As we
are convinced in the interest of Freee Software, Zinc is free
Software under LGPL.
Zinc is available at http://www.openatc.org/zinc or
http://freshmeat.net/projects/zincisnotcanvas/

People in charge of Zinc at CENA are good in producing good code.
They are not so good in producing extensive documentation and
examples.

This simple demo is a first try to demontrate the hidden power
behind Zinc.

If you feel happy with Zinc, feel free to contribute too!
One simple way is by producing simple samples like these
available in demo.pl

Please send us your production at pii-contact@cena.fr and
we will add it in the next release of Zinc.
